Yeap, that's certainly a challenge. I don't specifically know the
reasoning behind the name changing every update, though I'd venture a guess
that it involves Ms desire to only distribute these updates to GWV
customers, and perhaps some Microsoft Update distribution standards as
well.
The specific intent was to get you going with Defender, I suppose you could
ask for the name each update cycle in these forums... but that's pretty
lame sounding. How do you normally keep your Operating System up to date
if you can't access MsUpdates, surely you must have some process that keeps
you current? (like WSUS using a corporate server) Anyway I wanted to get
you going at least until you could get an alternative in place. There was
a past reference in these forums for how the Defender signatures get
authorized by the local admin if WSUS is the corporate update process, and
I'm in way over my head here already as I find Comcast Cable a plug & play
maze here at home.
Mention here how you normally update your OS critical updates... someone
here will know the answer...
